FIELD

In general, embodiments of the present disclosure relate to absorbentarticles that are disposable and wearable. In particular, embodiments ofthe present disclosure relate to disposable wearable absorbent articleswith elastics in multiple layers.

BACKGROUND

Disposable wearable absorbent articles include disposable diapers anddisposable incontinence undergarments (e.g., adult incontinenceproducts). A disposable wearable absorbent article can receive andcontain bodily waste while being worn by a wearer. Such articles can bemade with various materials in a number of configurations. The design ofa disposable wearable absorbent article can affect the way that thearticle performs while it is being worn.

Elastic materials can be configured as various elastic structures indisposable wearable absorbent articles. These elastic structures canfunction in different ways to provide various benefits to the wearer.For example, lower force elastics or elastics that are spaced apart canbe configured as shaping elastics. Shaping elastics can assist inproviding a conforming fit and distributing contact forces over thewearer’s skin. As another example, higher force elastics or elasticsthat are grouped closer together can be configured as anchoringelastics. Anchoring elastics can assist in holding the article in placeon the wearer by transferring loads from the article to particular partsof the wearer’s body.

Unfortunately, when a disposable wearable absorbent article includesdifferent elastic structures, those structures may not work welltogether. For example, if a disposable wearable absorbent articleincludes both shaping elastics and anchoring elastics, and thosedifferent elastic structures are not allowed to act somewhatindependently from each other, then their functions may be compromised.If the anchoring elastics transfer excessive loads to the regioncomprising the shaping elastics, they may concentrate forces against thewearer’s skin, causing discomfort and red marking. If the shapingelastics compromise the loads created by the anchoring elastics, thenthe anchoring elastics may not effectively transfer loads to intendedparts of the wearer’s body, potentially allowing the article to sag. Ifa disposable wearable absorbent article includes elastic structures thatdo not work well together, then the article may feel uncomfortable, lookunattractive, and perform poorly while it is worn by a wearer.

DETAILED DESCRIPTION

Embodiments of the present disclosure include disposable wearableabsorbent articles with different elastic structures that work welltogether. The different elastic structures may be separated intomultiple layers. For example, a disposable wearable absorbent articlecan include shaping elastics and anchoring elastics, which are separatedfrom each other by one or more layers of material. Since the shapingelastics are separated from the anchoring elastics, they can functionindependently of each other. The shaping elastics can at least assist inproviding a conforming fit and distributing contact forces over thewearer’s skin while the anchoring elastics can at least assist inholding the article in place on the wearer. As a result, the disposablewearable absorbent articles of the present disclosure can be easier toapply, feel comfortable, look attractive, and perform well while worn bywearers.

Absorbent articles include products for human sanitary protection, forhuman hygienic use, and the like. Some absorbent articles are wearable.A wearable absorbent article is configured to be worn on or around alower torso of a body of a human wearer. Examples of wearable absorbentarticles include diapers, training pants, and incontinence undergarments(including embodiments of each of these for people of all ages).

A disposable wearable absorbent article can include an absorbent core.Throughout the present disclosure, the term absorbent core refers to apart of a disposable wearable absorbent article configured to absorbbodily exudates (such as urine, menses, and feces) received into thearticle from a body of a wearer. An absorbent core can be configured invarious ways, as will be understood by one of ordinary skill in the art.An absorbent core can include one or more absorbent materials, such asabsorbent foams, highloft nonwovens, wood pulp and/or superabsorbentparticles, and may include one or more additional compositions,materials, or structures for receiving, containing, storing, and/ortreating bodily waste, as known in the art.

An absorbent core can be part of an absorbent assembly, comprising oneor more layers such as a liquid-permeable topsheet, an acquisitionlayer, a distribution layer, a storage layer, and a liquid impermeablebacksheet. Part, parts, or all of an absorbent core and/or part, parts,or all of an absorbent assembly may also include one or more of variousstructures, such as barrier leg cuffs, a feces containment compartment,a wetness indicator, fasteners for retaining the core within an article,disposal tapes, etc. Further, part, parts, or all of an absorbent coreand/or part, parts, or all of an absorbent assembly may include one ormore of compositions such as lotions, perfumes, and a sensate. Anabsorbent core and/or an absorbent assembly can be configured as abucket-shaped absorbent assembly, a removable absorbent core orabsorbent assembly, a replaceable absorbent core, etc.

A disposable wearable absorbent article can also include an outer cover.Throughout the present disclosure, the term outer cover refers to a partof a disposable wearable absorbent article forming an outer surface ofthe article (sometimes referred to as a backsheet), extending beyond theedges of the absorbent core, usually covering a significant portion ofthe buttocks of the wearer, and generally shaped to resemble theappearance of an undergarment. An outer cover can be configured invarious ways, as described herein. In various embodiments, an outercover can coincide with and/or define at least a portion of the chassisof a disposable wearable absorbent article.

Some absorbent articles are disposable. A disposable absorbent articleis configured to be disposed of after a single use (e.g., not intendedto be reused, restored, or laundered). Examples of disposable absorbentarticles include disposable diapers, disposable training pants,disposable incontinence undergarments, as well as feminine care pads andliners.

Elastic materials can be configured as various elastic structures indisposable wearable absorbent articles. These elastic structures canfunction in different ways to provide various benefits to the wearer.For example, lower force elastics or elastics that are spaced apart canbe configured as shaping elastics. Shaping elastics can at least assistin providing conforming fit and distributing contact forces over thewearer’s skin. As another example, higher force elastics or elasticsthat are grouped closer together can be configured as anchoringelastics. Anchoring elastics can at least assist in holding the articlein place on the wearer by transferring loads from the article toparticular parts of the wearer’s body.

Non-limiting types of elastic materials applicable for use in theembodiments disclosed herein include elastic strands, elastic ribbons,elastic films, elastic non-wovens, and combinations thereof. When thedescription details a plurality of elastics herein, it will be obviousto one skilled in the art that the term “plurality” refers toembodiments employing elastic strands and/or elastic ribbons or strips(as shown in the figure), however, in other embodiments, one or moreelastic films or elastic non-wovens may take the place of the pluralityof elastic strands and/or elastic ribbons.

The elastic material may be in the form of films, knitted fabrics, wovenfibrous webs or nonwoven fibrous webs. In some embodiments, the elasticmaterials may be in the form of extensible nonwovens or webs comprisingof polyolefinic fibers or filaments. Exemplary elastic materials aredisclosed in U.S. Pat. Nos. 7,819,853; 7,087,287; and 6,410,129; andU.S. Pat. Publication Nos. 2007/0287438; 2005/0164587; and 2009/0258210.

Suitable elastomeric compositions may be applied to a substrate in afluid or fluid-like state to affect at least partial penetration intothe substrate, thus, achieving sufficient bonding between the resultingelastomeric members and the substrate such that the composite resistsdelamination in the subsequent incremental stretching step. Theelastomeric composition may have a melt viscosity from about 1 to about150 Pa·s, preferably from about 5 to about 100 Pa·s, and more preferablyfrom about 10 to about 80 Pa·s, at 175° C. and 1 s⁻¹ shear rate. Suchelastomeric composition is suitable for use in the articles of thepresent invention.

Suitable elastomeric compositions comprise thermoplastic elastomersselected from the group consisting of styrenic block copolymers,metallocene-catalyzed polyolefins, polyesters, polyurethanes, polyetheramides, and combinations thereof. Suitable styrenic block copolymers maybe diblock, triblock, tetrablock, or other multi-block copolymers havingat least one styrenic block. Exemplary styrenic block copolymers includestyrene-butadiene-styrene, styrene-isoprene-styrene,styrene-ethylene/butylenes-styrene, styrene-ethylene/propylene-styrene,and the like. Commercially available styrenic block copolymers includeKRATON® from the Shell Chemical Company of Houston, TX; SEPTONⓇ fromKuraray America, Inc. of New York, NY; and VECTORⓇ from Dexco ChemicalCompany of Houston, TX. Commercially available metallocene-catalyzedpolyolefins include EXXPOL® and EXACTⓇ from Exxon Chemical Company ofBaytown, TX; AFFINITYⓇ and ENGAGEⓇ from Dow Chemical Company of Midland,MI. Commercially available polyurethanes include ESTANE® from Noveon,Inc., Cleveland, OH. Commercial available polyether amides includePEBAXⓇ from Atofina Chemicals of Philadelphia, PA. Commerciallyavailable polyesters include HYTREL® from E. I. DuPont de Nemours Co.,of Wilmington, DE.

Applicable nonwoven webs may comprise multicomponent fibers. Themulticomponent fibers will comprise a first component comprising apolypropylene composition having a melt flow rate of from about 100 toabout 2000 grams per 10 minutes and a second component comprising apolymer composition having a melt flow rate lower than the melt flowrate of the first component. The first component comprises at leastabout 10% of a surface of the multicomponent fiber. Typically, the ratioof the first component to the second component is from about 10:90 toabout 90:10. Preferably, the first component comprises at least about50% of the surface of the multicomponent fiber and more preferably, thefiber is a bicomponent fiber with the first component being a sheath andthe second component being a core. The polypropylene composition of thefirst component may comprise two or more different polypropylenes or apolypropylene and a different polymer. The second component willpreferably have a melt flow rate of from about 20 to about 80 grams per10 minutes and may be a low melt flow rate polypropylene or anythermoplastic composition. Preferably, the melt flow rate of the firstcomponent is from about 100 to about 1000 grams per 10 minutes and thesecond component has a melt flow rate of about 10 to about 80 grams per10 minutes. The nonwoven web may have a basis weight of from about 5 toabout 100 gsm and may be produced by a spunbound process. The diameterof the fibers comprising the web will typically be from about 5 to about50 microns. The nonwoven web may optionally comprise fibers other thanthe fibers comprising the polymer composition detailed above. The strainat peak load of the nonwoven web is preferably greater than 80% in atleast one direction.

The elastomeric film may be formed in a single layer or in a multi-layerstructure. The multilayer films may comprise two or more layers, atleast one of the layers being elastomeric. Although an elastomeric layeris generally substantially joined to one or two skin layers, it iscontemplated that multiple elastomeric layers may be utilized, eachelastomeric layer being joined to one or two skin layers. Three-layerfilms preferably comprise a central elastomeric core that may comprisefrom about 10 to 90 percent of the total thickness of the film. Theouter skin layers are generally, but not necessarily, identical and maycomprise from about 5 to 45 percent of the total thickness of the film.Tie layers, when employed, may each comprise from about 5 to 10 percentof the total film thickness. In a three-layer film, core layer hasopposed first and second sides, one side being substantiallycontinuously joined to one side of each outer skin layer prior to theapplication of applied stress to the web.

A particularly preferred multilayer film has an elastomeric layerinterposed between two skin layers. The elastomeric layer preferablycomprises a thermoplastic elastomer comprised of a substantiallycontinuous amorphous matrix, with glassy or crystalline domainsinterspersed throughout, the domains acting as effective physicalcrosslinks and hence enabling the material to exhibit an elastic memorywhen subjected to an applied strain and subsequently released. Preferredelastomeric materials include block copolymers and blends thereof, suchas styrene-butadiene-styrene or other such common styrenic blockcopolymers as are generally available from the Shell Company under thetrade name “KRATON.” Similarly, polyolefinic materials such aspolyethylene and polypropylene generally of densities below about 0.9g/cc could likewise exhibit the necessary thermoplastic character andresultant elastic behavior. The skin layers preferably comprise anythermoplastic polymer, especially polyolefinic polymers such aspolyethylene or polypropylene, generally of density greater than about0.9 g/cc which are capable of thermoplastic processing into thin films.The skin layer should have sufficient adhesion to the elastomeric layersuch that it will not completely delaminate either before or afterstretching of the web. A preferred method to produce the multilayerpolymeric film is coextrusion.

The elastomeric layer may provide the desired amount and force ofrecovery upon the relaxation of an elongating tension on theplastoelastic material, especially upon strain cycles following theinitial shaping strain cycle. Many elastic materials are known in theart, including synthetic or natural rubbers (e.g., crosslinkedpolyisoprene, polybutadiene and their saturated versions (afterhydrogenation), and polyisobutylene), thermoplastic elastomers based onmulti-block copolymers, such as those comprising copolymerized rubberelastomeric blocks with polystyrene blocks (e.g.,styrene-isoprene-styrene, styrene-butadiene-styrene,styrene-ethylene/butylene-styrene, styrene-ethylene/propylene-styrene,and styrene-butadiene/isoprene-styrene, including their hydrogenated andnon-hydrogenated forms), thermoplastic elastomers based on polyurethanes(which form a hard phase that provides high mechanical integrity whendispersed in an elastomeric phase by anchoring the polymer chainstogether), polyesters, polyether amides, elastomeric polyethylenes,elastomeric polypropylenes, and combinations thereof. Some particularlysuitable examples of elastic components include styrenic blockcopolymers, elastomeric polyolefins, and polyurethanes.

Other particularly suitable examples of elastic components includeelastomeric polypropylenes. In these materials, propylene represents themajority component of the polymeric backbone, and as a result, anyresidual crystallinity possesses the characteristics of polypropylenecrystals. Residual crystalline entities embedded in the propylene-basedelastomeric molecular network may function as physical crosslinks,providing polymeric chain anchoring capabilities that improve themechanical properties of the elastic network, such as high recovery, lowset and low force relaxation. Suitable examples of elastomericpolypropylenes include an elastic random poly(propylene/olefin)copolymer, an isotactic polypropylene containing stereoerrors, anisotactic/atactic polypropylene block copolymer, an isotacticpolypropylene/random poly(propylene/olefin) copolymer block copolymer, astereoblock elastomeric polypropylene, a syndiotactic polypropyleneblock poly(ethylene-co-propylene) block syndiotactic polypropylenetriblock copolymer, an isotactic polypropylene block regioirregularpolypropylene block isotactic polypropylene triblock copolymer, apolyethylene random (ethylene/olefin) copolymer block copolymer, areactor blend polypropylene, a very low density polypropylene (or,equivalently, ultra low density polypropylene), a metallocenepolypropylene, and combinations thereof. Suitable polypropylene polymersincluding crystalline isotactic blocks and amorphous atactic blocks aredescribed, for example, in U.S. Pat. Nos. 6,559,262, 6,518,378, and6,169,151. Suitable isotactic polypropylene with stereoerrors along thepolymer chain are described in U.S. Pat. No. 6,555,643 and EP 1 256 594A1. Suitable examples include elastomeric random copolymers (RCPs)including propylene with a low level comonomer (e.g., ethylene or ahigher α-olefin) incorporated into the backbone. Suitable elastomericRCP materials are available under the names VISTAMAXX (available fromExxonMobil, Houston, TX) and VERSIFY (available from Dow Chemical,Midland, MI).

The embodiments of FIGS. 1A through 3E describe different types ofdisposable wearable absorbent articles with various embodiments ofelastics in multiple layers.

FIG. 1A illustrates a plan view of a belt type disposable wearableabsorbent article 100, which includes a first embodiment of elastics inmultiple layers. FIG. 1A illustrates a plan view of a belt typedisposable wearable absorbent article 100. The view of FIG. 1Aillustrates an inside (wearer-facing side) of the article 100.

Throughout the present disclosure, a reference to a belt type disposablewearable absorbent article can refer to an embodiment that is fastenableor to an embodiment without fasteners. A reference to a belt typedisposable wearable absorbent article can also refer to an embodiment ofan article with one or more waist and/or leg openings that are preformed(i.e. formed during manufacture of the article) or to an embodiment ofan article with waist and leg openings that are not preformed. Thus,each embodiment of a disposable wearable absorbent article of thepresent disclosure that is described as belt type can be configured inany of these ways, as will be understood by one of ordinary skill in theart.

In FIG. 1A, a longitudinal centerline 113 and a lateral centerline 117provide lines of reference for referring to relative locations of partsof the article 100. When a first part is nearer to the longitudinalcenterline 113 than a second part, the first part can be consideredlaterally inboard 112 to the second part. Similarly, the second part canbe considered laterally outboard 114 from the first part. The first partwould be proximal relative to the second part and the second part wouldbe distal relative to the first part. When a third part is nearer to thelateral centerline 117 than a fourth part, the third part can beconsidered longitudinally inboard 116 to the fourth part. Similarly, thefourth part can be considered longitudinally outboard 118 from the thirdpart. The third part would be proximal relative to the fourth part andthe fourth part would be distal relative to the third part. Throughoutthe present disclosure, when one part is simply referred to as inboardfrom another part, the one part is laterally inboard and/orlongitudinally inboard from the other part. In the same way, when onepart is simply referred to as outboard from another part, the one partis laterally outboard and/or longitudinally outboard from the otherpart.

FIG. 1A includes arrows indicating relative directions for laterallyinboard 112, laterally outboard 114, longitudinally inboard 116, andlongitudinally outboard 118, with respect to the article 100. Throughoutthe present disclosure, unless otherwise stated, a reference to alongitudinal dimension, measurement, line, or direction refers to adimension, measurement, line, or direction substantially or completelyparallel to the longitudinal centerline 113, and a reference to alateral dimension, measurement, line, or direction refers to adimension, measurement, line, or direction substantially or completelyparallel to the lateral centerline 117.

The article 100 includes a front 124 and a back 126. The front 124 is aportion of the article 100 disposed generally proximate to and/or belowthe belly of a wearer, when the article 100 is worn by the wearer. Areference to the “front” can mean the front itself, part, or parts, orsubstantially all, or all of an element in the front, and/or adisposition in the front, depending on the context of the reference. Theback 126 is a portion of the article 100 disposed generally proximate toand/or below the back of a wearer, when the article 100 is worn by thewearer. A reference to the “back” can mean the back itself, part, orparts, or substantially all, or all of an element in the back, and/or adisposition in the back, depending on the context of the reference. Thelateral centerline 117 of the article 100 divides the articlelongitudinally into halves and forms a boundary between the front 124and the back 126. The terminology for front and back, described above,is used for disposable wearable absorbent articles throughout thepresent disclosure, unless otherwise indicated.

The article 100 includes a belt 160 and a center chassis 120. A frontbelt portion 161 and a back belt portion 169 form the belts 160. Thearticle 100 includes an absorbent core 127 that extends from the frontbelt portion 161 through the center chassis 120 to the back beltportion. The center chassis 120 includes a topsheet 106 that is inwardto the absorbent core 127 and a backsheet 107 that is outward from theabsorbent core 127.

The front 124 includes a front belt portion 161 with a front waist areathat is adjacent to a front waist edge 109 and is one-third toone-quarter of the overall longitudinal length of the article. The back126 includes a back belt portion 169 with a back waist area that isadjacent to a back waist edge 104 and is one-third to one-quarter of theoverall longitudinal length of the article. The center chassis 120includes a crotch region disposed between the front waist region and therear waist region, wherein the crotch region includes the lateralcenterline 117. The absorbent core 127 extends from the front 124 to theback 126.

The front belt portion 161 has a front inner belt portion 162 and afront outer belt portion 165, as illustrated in FIGS. 1B and 1C. Thefront inner belt portion 162 includes a plurality 195 of front shapingelastics 197. The plurality 195 is configured in the same way as theplurality 495 of the embodiment of FIG. 4A. The front outer belt portion165 includes an anchoring system 130, with anchoring elastics 141. Theanchoring elastics 141 of the anchoring system 130 are configured in thesame way as the plurality of shaping elastics 895 of the embodiment ofFIG. 8B, except that the elastics are anchoring elastics, which worktogether in the form of a Circumferential Anchoring Member (CAM) asdefined and described herein, similar to the front CAM 1141 of theembodiment of FIG. 11B. Together, the plurality 195 of front shapingelastics 197 and the plurality of anchoring elastics 141 form the firstembodiment of elastics in multiple layers.

The terms inner and outer as they apply to the inner belt portion andouter belt portion are intended to provide a relative position of thetwo portions in relationship to each other. In other words, the innerbelt portion is positioned closer to the wearer-facing surface of thearticle than the outer belt portion and the outer belt portion ispositioned relatively closer to the garment-facing surface of thearticle than the inner belt portion. In certain embodiments the innerbelt portion may form part of the inner, wearer-facing, surface of thearticle and the outer belt portion may form part, or all, of the outer,garment-facing, surface of the article. One or both of the inner beltportion and the outer belt portion may be disposed outwardly of thebacksheet or alternatively inward of the backsheet.

The inner and/or outer belts may be formed in a variety of shapes. Theinner and outer belts may be rectangular or may have inner and outerlongitudinally opposed edges that are concave with regard to the waistedge and lateral axis. The shape may also substantially follow the shapeor curvature of the elastics disposed in the respective belt structure.

In the embodiment of FIG. 1A, the back belt portion 169 has no elastics.However, in various embodiments, the back belt portion 169 can beconfigured in the same way as the front belt portion 161 or the backbelt portion 169 can have elastics configured in a different way.Moreover, for the embodiment of FIG. 1A, as well as any other embodimentdisclosed herein, any configuration of shaping and/or anchoring elasticsdisclosed in the front or the back of the absorbent article may becombined in part or in whole with any other configuration of elasticsdisclosed in the other respective end of the absorbent article. In otherwords, absorbent article embodiments are contemplated herein that areformed from any front belt portion disclosed herein integrated in partor in whole with any back belt portion disclosed herein.

FIG. 1B illustrates an exploded cross-sectional side view of the frontbelt portion 161 of the article 100 of FIG. 1A, taken at a firstsectional line. FIG. 1B includes an inward direction 111 (toward thewearer, and away from the outer garment) and an outward direction 119(away from the wearer, and toward the outer garment). This terminologyfor inward, inner, outward, and outer, is used for disposable wearableabsorbent articles throughout the present disclosure, unless otherwiseindicated.

The front inner belt portion 162 includes an inner belt layer 163, theplurality 195 of front shaping elastics 197, and an outer belt layer164. The belt inner layer 163 is the innermost belt layer. The plurality195 of front shaping elastics 197 is outward 119 from the inner beltlayer 163. The outer belt layer 164 is outward 119 from the plurality ofshaping elastics 197. In various embodiments, the plurality 195 of frontshaping elastics 197 can be joined to either or both of the inner beltlayer 163 and the outer belt layer 164.

The inner belt layer 163 and/or the outer belt layer 164 can be anonwoven, a film, a laminate that includes a nonwoven and a film, or anyother kind of material suitable for forming a layer of material. Invarious alternative embodiments, the inner belt layer 163 or the outerbelt layer 164 may be omitted. In various alternative embodiments, thefront inner belt portion 162 can also include one or more additionalmaterials or layers.

The embodiments of FIGS. 9A through 11B describe various anchoringsystems for use in disposable wearable absorbent articles. Theseanchoring systems can be configured with one or more CAMs, anchoringbands, LDEs, spines, and/or other anchoring pathways, in various ways,as described herein. In FIGS. 9A through 11B, for the purpose ofclarity, some parts of the disposable wearable absorbent articles areillustrated as transparent, to show structures and features, which theoverlying material might otherwise hide.

With regard to anchoring, the present disclosure uses the followingterminology. The term “anchoring system” refers to one or more anchoringpathways, wherein the anchoring system can at least assist in holding adisposable wearable absorbent article in place on a wearer’s body, asdescribed herein. The term “anchoring pathway” refers to one or moreanchoring elements, configured as a tension-carrying pathway, whichtransfers a load from the portion of the chassis comprising theabsorbent core to an anchoring location on the body of wearer of thearticle, as described herein.

The term “anchoring elements” refers to one or more separatelyidentifiable structural elements, which form part of an anchoringsystem. Some anchoring elements can be configured to collect loads fromthe disposable wearable absorbent article, as described herein. Forexample, anchoring elements can be joined to the absorbent core and/orabsorbent assembly. Some anchoring elements can be configured totransfer loads in an anchoring system, as described herein. For example,anchoring elements can be configured to carry tension along an anchoringpathway. Anchoring elastics can be anchoring elements. Some anchoringelements can be configured to provide holding forces through contactwith the body of a wearer at one or more anchoring locations, asdescribed herein. The term “anchoring location” refers to a location ona wearer’s body, which is capable of supporting a load transferred froman anchoring pathway, as described herein.

The term “anchored” refers to the use of an anchoring system to hold adisposable wearable absorbent article in place on the body of a wearer.When a disposable wearable absorbent article is anchored to a portion ofthe body of a wearer, the anchoring system is configured to at leastreduce and/or prevent relative movement between article and that portionof the body, while the wearer wears the article. A disposable wearableabsorbent article with an anchoring system can be anchored to a body ofa wearer with one or more anchoring elements of the anchoring systemconfigured to directly and/or indirectly (e.g. through other layers ofmaterial) overlie and/or contact one or more of various anchoringlocations on parts of a body of a wearer.

A part of the body with a relatively smaller radius of curvature can, insome embodiments, act as an anchoring location that provides relativelygreater friction forces, since an anchoring element can tend to wraparound such parts more tightly. This is due to the physics of a flexiblematerial that is wrapped around a curved surface and placed undertension. In this scenario, as a tensile force places the flexiblematerial under tension, the flexible material exerts a normal forceperpendicular to and inward on the curved surface. According to thebasic Capstan formula, the normal force is proportional to the tensileforce divided by the radius of the curved surface. Thus, at a giventensile force, as the radius becomes smaller, the normal force becomeslarger.

Also as an example, an anchoring system can be at least partiallyanchored by setting one or more anchoring elements on, around, and/orabove one or more anchoring locations that protrude from the body, thuscreating friction and/or reaction forces. A part of the body with arelatively larger horizontal protrusion can, in some embodiments,provide greater reaction forces, since an anchoring element can tend tohang and/or ride on or above such parts more securely (i.e., there is anupward component to the reaction force from the body that can support aload).

An anchoring pathway can be configured in various forms. An anchoringpathway can be made from any material suitable for carrying tensions inan anchoring system. Part, or parts, or substantially all, or all of ananchoring pathway can include one or more anchoring elements made ofvarious suitable materials (such as a plurality of anchoring elastics).An anchoring pathway can be a unitary, continuous pathway, or can beformed by any number of anchoring elements disposed (in series or inparallel) along a pathway. Part, or parts, or substantially all, or allof an anchoring pathway (and its anchoring elements) can be straight,curved, angled, segmented, or other shapes, or combinations of any ofthese shapes. In some embodiments, an anchoring pathway can include oneor more connecting elements, such as belts, seams, and/or fasteners.

An anchoring element can be of any suitable size, shape, andconfiguration. The size and/or shape of an anchoring element can besubstantially or completely uniform over one or more parts of theanchoring element or over the entire length of the anchoring element, orcan vary over the length of the anchoring element.

In various embodiments, anchoring elastics can be used as anchoringelements. Anchoring elastics can be formed from various materials, suchas the materials described herein for shaping elastics. Anchoringelastics can have a decitex ranging from 250 to 2500, or any integervalue for any decitex value in this range, or any range formed by any ofthese integer values.

Part, or parts, or substantially all, or all of any anchoring elementcan be separate from, and/or structurally associated with, and/or joinedto, and/or attached to, and/or durably attached to, and/or refastenablyattached to, and/or embedded in, and/or integral with one or more otherelements (such as an outer cover and/or a waist cover and/or anabsorbent core) of a disposable wearable absorbent article. As usedherein, the term “joined” refers to configurations wherein an element isdirectly secured to another element and to configurations wherein anelement is indirectly secured to another element by connecting theelement to one or more intermediate members, which are, in turnconnected to the other element.

When an anchoring pathway is formed by one or more anchoring elementsembedded in or integral with one or more other elements, the anchoringpathway forms a distinct and recognizable anchoring pathway within thatstructure. For example, when anchoring elements that are integral withan outer cover forms an anchoring pathway, the anchoring elements canform an anchoring pathway with a substantially higher modulus ofelasticity than areas of the outer cover surrounding the pathway.

Anchoring pathways disposed on surfaces within a disposable wearableabsorbent article are intended to align with anatomical pathways definedon the external surfaces of a body of a wearer of the disposablewearable absorbent article in which the anchoring system is included.The shapes of the anatomical surfaces can affect the shapes of theanchoring pathways. The shapes of the anchoring pathways can, in turn,affect configurations of anchoring elements.

One kind of anchoring pathway is an anchoring band. An anchoring bandcan be configured to transfer tensile forces from one end to the otherand to have sufficient strength to carry such tension in an anchoringsystem. In various embodiments, an anchoring band can at least partiallyencircle a lower torso of the body of the wearer, for example in theback portion of the article.

Another kind of anchoring pathway is a load distribution element (LDE).An LDE is a type of anchoring pathway that transfers loads in ananchoring system of a disposable wearable absorbent article. An LDE canreceive at least some collected loads by being joined to one or moreother elements of the disposable wearable absorbent article, such as anabsorbent core. Also, an LDE can transfer such loads to one or moreanchoring locations or anchoring pathways, such as a circumferentialanchoring member (CAM) or anchoring band. In various embodiments, LDEscan be configured to transfer part, or parts, or substantially all, orall of loads from an absorbent core absorbent assembly to other portionsof a disposable wearable absorbent article, for example the belt or sidepanels, waist elastics or leg elastics of the absorbent article.

Yet another kind of anchoring pathway is a spine. A spine is a type ofanchoring band that helps support a load in the absorbent core in ananchoring system of a disposable wearable absorbent article. A spine isoriented either substantially or completely laterally or substantiallyor completely longitudinally. A substantial portion of a spine passesthrough an area of an absorbent core or absorbent assembly of adisposable wearable absorbent article. In some embodiments,substantially all or all of a spine can be contained within an area ofan absorbent core.

A CAM is another kind of anchoring pathway that generally follows acurved surface within a disposable wearable absorbent article or on abody of a wearer. A CAM at least partially encircles a lower torso ofthe body of the wearer. In some embodiments, a CAM can substantially orcompletely encircle the lower torso of the body of the wearer. While aCAM may follow a curved pathway while a wearer is wearing the article,the CAM may be substantially or completely linear when the article islaid out flat.

Further, portions of the anchoring systems disclosed herein may beformed from the same elastics. For example, portions of the CAMs andLDEs may be formed from the same elastic. In other words, an elastic canbe fed along the waist from the edge inward towards the longitudinalcenterline and then diverted inward toward the lateral centerline toform one of the LDEs and then diverted outwardly towards the waist edgeand then diverted again towards the side edge of the belt.

In FIGS. 9A through 11B, for ease of illustration, each of the anchoringpathways is shown as a unitary structure. However, each of theseanchoring pathways may formed by a plurality of anchoring elements,which are anchoring elastics. In various alternate embodiments, any ofthese anchoring pathways can be configured in any manner describedherein. Each of these anchoring systems of FIGS. 9A through 11B can beconfigured in a disposable wearable absorbent article to anchor anabsorbent article and/or absorbent core to a wearer. In variousembodiments, each of these anchoring systems can be configured in adisposable wearable absorbent article to carry part, or parts, orsubstantially all, or all of the loads from the absorbent core andexudates introduced into the absorbent core by the wearer of thearticle.

FIG. 9A illustrates a plan view of a front/side fastenable disposablewearable absorbent article 901, which includes an anchoring system 930.Each of the general elements of the embodiment of FIG. 9A is configuredin the same way as the like-numbered element of the embodiment of FIG.1E.

Also, in any of thesealternate embodiments, one or more anchoring bands could be used alongpart, or parts, or substantially all, or the entire pathway of the backCAM 931. Further, any of these alternate embodiments could be combinedin whole or in part to create additional alternate embodiments.

There are two back LDEs 933, one on each side of the longitudinalcenterline 913. For the back LDE 933 to the right of the longitudinalcenterline, one end of the back LDE 933 connects to the back portion ofthe spine 935 at a location longitudinally offset from the lateralcenterline 917. A portion of that back LDE 933 may underlay a portion ofthe absorbent core 927, and may be joined to that portion. That back LDE933 extends straight from the back portion of the spine 935, laterallyand longitudinally outward, and connects to the back CAM 931. The firstback LDE 933 is considered an LDE because, when the article 901 is wornby a wearer, the first back LDE 933 is configured to transfer at leastpart of the load from the absorbent core 927 to the back CAM 931. Theback LDE 933 on the left is configured in the same way, though mirroredby the longitudinal centerline 913.
